Abstract: Yunnan is cured country, but special machinery and equipment design and manufacturing level is low, the development and use of infancy. Distributing in a mountainous area tobacco region, still with animal , manual operation, limiting the labor efficiency and raising the level of modern. Therefore, this study intends to design of use Solid Works software and flue-cured tobacco supporting the weight of the light intensity is good, easy to install micro-ridge, the main research of rotary tillers supporting flue-cured tobacco ridging bodies planting in hilly smaller plots smooth operations, improve the adaptability to make up for the deficiencies of the large ridge.

Abstract: The thermal response for given micromachine with the boundary surface exposed to sudden temperature change is studied by deriving an analytical solution of the hyperbolic heat conduction equation. Using the obtained analytical expression, the temperature profiles at the outer surface and interior of the micro beam are evaluated for various thermal relaxation times. The behaviors of hyperbolic heat propagation in micro beam are analyzed and possible anomalies are discussed by comparing the thermal behaviors of Fourier heat conduction.

Abstract: With the micromachining technology, two perpendicular cavities are formed on a silicon substrate, and two thermistors whose resistances are equal are placed parallel in each cavity. The nature convention of the gas is produced by the thermistors which are used as both the heater and the sensitive element in the hermetic cavity, and the acceleration can be measured with the temperature difference sensed by the thermistors. At last the test about the sensor shows when the value of acceleration is at the range of ±7g, the non-linearity is less than 0.62%FS.

Abstract: . Error autocompensation using a non-MEMS micromotor is used to reduce the drift of micromachned gyroscopes. Theoretic deviation, numerical simulation and experiments are carried out. Test results show that the bias instability of micromachined gyroscopes is reduced from 542°/h to 39°/h, which makes their high end applications possible
